That sounds like a good place to start. Then move on to the Build of your choice. For people without an A-Race, you can simple reset back to the SSB1 & SSB2, with a different Build for fun and variety. There is not much need to do a Specialty, but you can always do one for something different.
I would include a short break from structure after your first Build. Like the 1 or 2 week reset that is recommended after people complete the Specialty and A-Race.
